Tired

By | | , ,
3 Comments

It has been rather a tiring last several days. I’ve been focusing on writing a big report on various internal matters that my committee was charged to study for the whole academic year. The issues are rather large, and the solutions I was trying to present require not just cosmetic tinkering but major changes in the way things are done. So the key thing to get right in writing it is a tone that is critical of what there currently is in place while at the same time painting a picture of what could be in its stead, while also beginning to show how to get there. If you don’t balance all three just right, there’s no chance that anything will change, since either lots of people will just be pissed off that you trashed their system, or threatened the status quo, or they’ll agree but say there’s nothing that can be done, or they’ll say you have not really thought it through. I think I’ve managed to get the balance right.

It was due on Monday. On Sunday night, I had something down, but I did not really like […] Click to continue reading this post →

Major Cyclone

Update: 11th May ’08. Well, as you probably know, estimates have surpassed 100,000. An urgent concern now is the additions to the death toll resulting from the lack of emergency relief, brought on by the restrictions placed by the Myanmar government. See a BBC report here, or an NPR report here, for example.

Update: 7th May ’08. It is much worse. I’ve seen a BBC report with a figure above 22,000.

The news is not good for Myanmar (Burma). The death toll due to cyclone Nargis has apparently passed 10,000 (see CNN and the BBC), making it the deadliest storm since 1999.

Sheril and Chris are blogging about it on the Intersection, (see e.g. here) and so keep […] Click to continue reading this post →

JPL Open House!

Oh! It is the open house for the Jet Propulsion Laboratory this weekend! I almost missed it since it was two weekends later last year. Image composite brazenly taken from their website.

JPL Open House

I went last year and had a great time and so I strongly recommend it. Go along for your own interest, of course, but if you have any kids, take ’em along*. If interested, have a look at my detailed post from last year entitled “JPL the new Disneyland?”

As I said there: […] Click to continue reading this post →

Oh Dear, I Liked Ken…

Oh dear, I liked Ken. Now he’s gone from office. Ken Livingstone really understood public transport and did something about it. And the congestion charge…(which was my idea!!!)… took someone with real guts to push it through. We need more people like him to fight the car lobby – to get people to change their behaviour and do something for their environment.

Thanks, Ken.

Sad Ending

sam smith’s oatmeal stoutThat’s it. The class is over… I have to admit that I’m pretty sad to see the end of it, although I’m very very tired. It was such a great group. (I’ll be toasting the end of it all with some of the splendid stuff to the right.)

Recall that we stepped away from black holes. After a look at cosmology for some lectures, where we understood the role of four crucial components in determining a universe’s properties (curvature, matter, radiation, and vacuum energy) we dove back into formalism for a short while (one lecture) to develop a little more the tools we needed to properly under stand how to formulate Einstein’s field equations.

It did not take long… You need only the idea that it makes sense to formulate everything in terms of objects that allow you to express the full sense of an equation in any coordinate system you care to write. Once that is done (the objects are called tensors, and the idea and how they work is pretty simple to get to grips with) the key to formulating the field equations of gravity is to have a look at the structure of other familiar systems. The field equations of electromagnetism (Maxwell’s equations) and the field equations for Newton’s formulation of gravity give the required clues. A rummage around the geometry to find the appropriate object to express the physics in terms of uncovers the Riemann tensor and its cousins (“contractions” to get Ricci and so forth), and you’re almost there. A step back to learn how to package energy […] Click to continue reading this post →

Center For Inquiry: Chris Mooney on The War

Well, here’s a turn up for the books. I pass the buildings of the Center for Inquiry (West) in Hollywood quite regularly on my to-ings and fro-ings, and always wondered what it was. About what were they inquiring? My inquiring mind wanted to know, but by time I got back to a computer, I’d forgotten all about intending to Google it. I was sort of expecting that it might be some, er, fringe organization, given the neighbourhood (not 1/4 of a mile away is uncle charles - center for inquirythe mother ship (or one of them) for the Scientologists, and a similar distance in the other direction is the “Scientology Celebrity Centre” too, where John, Tom, Kirstie, and others from the remarkably large movie star Scientology set presumably go and hang out and feel… celebrated).

Well, it turns out that it’s not like that after all, but a place where, as far as I can tell, serious reason-based inquiry into issues surrounding the places where, e.g., science, religion, culture and superstition intersect (such as, you know, real life) is encouraged. I like that poster of theirs I found, for example (image to the right).

They have a number of speaker series, where all sorts of interesting people come to speak, and people come to […] Click to continue reading this post →
